Thread: proof that the proof that .999_ = 1 is not a proof (version)

Hello,

I think that this is a proof... As we're just using the fact that ... Don't you agree ?

Edit : ok, was talking about another version of the proof...

Why wouldn't we multiply an infinite expansion ? Thus your sentence 0.33......=1/3 is supposed to be false too...
D'you think you're revolutionnating mathematics ?

please respond and let me know what you think - but try not to tell me anything that i already know (e.g. that i am useless and genius, charismatic and disrespectful, and theoretical and practical at the same time).

oddly enough, the only reason for you to respond is that there is no reason to respond.

I can't see your attachment, but this topic has already been discussed (and consequently locked)

edit: Okay, you fixed the attachment

edit2: Also, the proof for .999=1 that you argued against is not the proof that mathematicians use.

edit3: Don't be too discouraged, though. I believe math is the only objective truth which exists, but I am still wary of mathematicians :P Skepticism is healthy.
